A breakthrough in heat transfer technology

21.07.2003

A revolutionary breakthrough in heat transfer technology that could improve process productivity and reduce energy consumption and waste, is being developed by Ashe Morris Ltd thanks to a £100,000 investment from NESTA (the National Endowment for Science, Technology & the Arts), the largest source of early stage funding in the UK.

Heat exchangers are used in many industrial, commercial and domestic applications and can be used to add or remove heat during chemical and biological manufacturing processes. In a batch manufacturing environment, such as fermenting beer, or making pharmaceuticals, current heat exchangers control the temperature of the process (where the reaction occurs) by regulating the heat transfer fluid temperature or the flow rate as it passes through a cooling jacket.

Ashe Morris is developing a new technology that controls the temperature by changing the effective heat transfer area itself to control the process temperature. In a batch manufacturing application, the heat transfer fluid will flow around up to 100 independent elements that are controlled by a multi-port linear valve with a piston. As the piston moves up and down the valve it brings the relevant elements into use and heats or cools that section.

This is simple innovation has many unique and innovative aspects to it. The design could offer more precise and fast temperature control and increase yield and quality in processes that are sensitive to shifts in temperature. This will, in turn, reduce chemical waste and the costs associated with recycling waste products.

It can also utilise calorimetry principles – which, for the first time, can now be used to measure the amount of heat evolved or absorbed in a chemical reaction in any size of plant. This method – unlike existing systems - allows for a reaction to be monitored and altered while it is in process. As a result, progress can be regularly checked, conditions optimised and potential problems avoided.

Furthermore, Ashe Morris believes that the new technology can reduce energy consumption by up to 90% in specific applications - thus reducing emissions. The system is also easily retrofitted so companies would not need to abandon existing equipment to benefit from the new technology.

Jeremy Newton, Chief Executive of NESTA, said: "Despite generating considerable market interest Ashe Morris was stuck in an early stage equity gap and needed to secure funding to develop the project. A NESTA Invention & Innovation award of £100,000 will do just that, helping to take this unique idea to the next stage of investment. This idea is both brilliant and simple and could be an excellent investment for NESTA and the UK as a whole."

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
